IMPROVEMENT IN STEAM-TRAPS.

Schedule referred to inthese Letters Patent'and making part of the same.

1,TAuns lllrnsouv Honens, of thexcty of -Baltimore, in the State of Maryland, have invented an Improved Steam-Trap,lwhich is described as follows:

Nature and Objects Vofr the Invention..

My invention relatescspecially to that class of steam-traps which isemployed to prevent the escape of steam, while permitting the discharge of water of condensation from coils 'orother radiators, which are heatedby steam.

The improvement consists in constructing the main pipe, at or near its discharge end, or at any point where it is desired to, discharge the water and-trapl the steam, witha diaphragm or partition to arrest the iiow, and'some distance back of said partition a lateral opening, which isguarded .by a screw, plug, or valve, and communicates with a duct by which any water or steam which passes` the valve is carried around the Y partition auddelive'red into the discharging end ot the main pipe. i,

Suitable plugs are provided for the purpose of removing anysediment or impurities which may collect upon or againstthepartition. Ixrtlle main pipe or at 4the lower `part of the connecting-duct-or instead of one or both of` these plugs, cocks may be employed, which, in addition to the functions alreadystated, may be employedlto draw water of condensation from the pipes or permit a slight escape of'steain.`

General Description with Reference to the Drawings.

being its receiving and a.` its discharging end.

Between theseends thepipe-is divided by a perma-r nent partition, B. l

At some distance from the partition B, toward the receiving end of the pipe, is alateral opening, C, which is preferably lined with a bushing, c, bitt or other metalsuitable to form a valve-seat, upon which works a valve, d, formed on the end of a screwplug, D, which works within a threaded socken-E, and isrotated by means of a hand-wheel, F, in customary manner. i i

G `mayfrepresenl. a cap and packing of common form. l

y 4ISI represents a duct, leading from the aperture at G to another aperture, I, which communicates with the main pipe on` the discharging side of the Apartiportion of asteam-coil, provided atits ends, a and a/with `screw-threads for coupling, a

of brass, or Bab-z The said `duct is formed in a'projection, J, on the side of the m'ain pipe.

K represents a screw-plug. closing au aperture in the main pipe directly above the partition B, which is employed for the purpose of discharging any'sediment or accumulation of impure or solid matter from -the pipe.

, L is a plug, closing an aperture in the lowestpart of the projection J, employed'for like cleansing of the 'duct H.

' The main pipe A, with its partition B, the socket E, and projection J, with their apertures at C, H, K, aud L, are all east in one piece 0i' iron or other metal, in an inexpensive manner, and the `necessary screwthreads are readily tapped in. f

Operation aperture I, and delivered into the dischargingnend of f the main pipe. i

When it is desirable to retain the water ot' condenf `sation for any purpose, instead of letting it pass ott through the waste-pipe, a small spigot or other device maybe inserted in place of the plug L, or the same steam wit-hin the apartment.

The following is claimed as new: Y

1. The partition B, duct H, and plug orvalve D d, apertures O I, when combined and arranged in connection with the main pipe A, in the manner: and for the purposes specied.

2. The plugs K and L, (or a cock or cocks in lieu of either or both,) in combination with the main pipe A, partition B, and duct H, substantially as and for the purposes set forth. I
